Evidence of introduced honeybees (Apis mellifera) as pollen wasters in orchid pollination
Scientific ReportsBiological invasions threaten global biodiversity, altering landscapes, ecosystems, and mutualistic relationships like pollination. Orchids are one of the most threatened plant families, yet the impact of invasive bees on their reproduction remains ...

Different Physiognomies and the Structure of Euglossini bee (Hymenoptera: Apidae) Communities
Sociobiology, 2018 Our aim was to evaluate the occurrence of orchid bees in remnants of the Atlantic Forest. We sampled specimens from five regions of Southeast Brazil, covering three different physiognomies of the Atlantic Forest (mixed Araucaria forests with high ...

Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity
Journal of Applied Entomology, Volume 150, Issue 8, Page 1153-1163, September 2026.ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective
Advanced Science, Volume 13, Issue 47, 24 August 2026.Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

Foliar salt spray exclusion and tissue tolerance underlie local adaptation to oceanic salt spray
American Journal of Botany, Volume 113, Issue 8, August 2026.Abstract Premise Surviving the effects of oceanic salt spray is critical for plants in coastal ecosystems, yet the mechanisms of coastal plant resilience to salt spray are not well understood. We investigated mechanisms of salt spray adaptation by comparing five latitudinal pairs of yellow monkeyflower accessions locally adapted to coastal and inland ...

Ecology and evolution of pyrazines in insects
Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Fluorescent colors in orchid bees (Hymenoptera: Apidae) [PDF]
Neotropical Entomology, 2005 The presence of UV-fluorescent pigments is described for the first time in insects. The clear hairs on terga I, III and IV of Eulaema niveofasciata (Friese) are the only ones among several Euglossina species which fluoresce, supporting recent taxonomic studies which suggested that this endemic species of the Atlantic Forest domain and Eulaema ...
